United States Patent 07 CHLORHWATOR FOR MARINE TOILETS Perry Belden, Highland Park, NJ. (Apt. 13A Arlene Village, Millville, N J.)

Filed June 19, 1958, Ser. No. 743,034

2 Claims. (Cl. 4-222) The present invention generally relates to an attachment for a marine toilet and normally arranged in adjacent relation thereto for bacterially cleaning the waste matter by injection of a chemical and by the use of a rotatable mixing blade to disintegrate the waste matter and thoroughly mingle the same with water so that only unobjectionable waste will be discharged overboard.

One of the most objectionable features of boating is the discharge of waste matter into the water in which the boat is floating. Solid particles of waste matter along with paper quite often float creating an extremely hazardous health condition and generally being objectionable in appearance as well as odor. Accordingly, in order to overcome these objections, the present invention provides a compartmented container including a first compartment and a second compartment with the first compartment receiving the waste from a conventional soil pump which is connected with a siphoning device for siphoning a small amount of sodium hypochlorite into the incoming flow of water and on into the first compartment where a chlorinating action takes place. The second compartment of the container is separated from the first compartment by partitions having openings adjacent the upper wall and the first compartment is provided with a driven agitator for breaking up, grinding, beating, churning and blending the waste matter into a liquid with very small particles of solid material therein, and the second compartment of the container permits further chemical action to take place in continued chemical cleaning of the waste before it is discharged into the outside water.

A further object of the present invention is to provide a chlorinator in accordance with the preceding objects which is extremely simple in construction, easy to install, easy to clean, well adapted for its intended purposes and relatively inexpensive to manufacture.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawing forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a perspective view with portions broken away of the chlorinator of the present invention installed in relation to a conventional marine toilet;

Figure 2 is a longitudinal sectional view of the chlorinator illustrating the structural arrangement thereof.

Referring now specifically to the drawings, the numeral generally designates the chlorinator of the present invention which is used in conjunction with a marine toilet of a conventional construction which is generally designated by the numeral 12 and includes the usual com- 'mode bowl 14, seat 16, cover lid 18' ad mounting brackets 20 connected to the bowl 14 and provided with a trans- Patented S p 6,4960

2. is a soil pump generally designated by the numeral 32 and which is of conventional construction and provided with an operating handle 34 at its upper end disposed alongside of the seat 16 for ease of operation thereof. The soil pump 32receives the Waste from the bowl through the tubular base fitting 24 and discharges the same through an outlet adapter 36.-At the same time, the upper part of the soil pump 32 receives water'from an inlet 38 through a control valve 40 and the water is discharged through a discharge pipe 42 into the commode bowl 14 for flushing the same in the usual manner; Disposed alongside of the commode bowl 14 is an enlarged container 44 containing sodium hypochlorite which is provided with a siphoning tube 46 in the open end thereof with the siphoning tube 46 beingconnectedto a'conduit 48 extending to the central side of the water part of the soil pump 32 for effecting pumping and siphona ing of the sodium hypochlorite into the incoming flush water. Thus, with the present invention, the'soilpump 32 will pump the water and waste matter together with the sodium hypochlorite outwardly through the discharge adapter 36 into a tubular member 50 connected with an inlet opening 52 in an enlarged tank 54 having a removable top wall 56 secured in position by fastening bolts 58 extending through a peripheral inturned flange 60. The inlet 52 is disposed adjacent the top of one side of the tank 54 and an outlet adapter 62 is provided adjacent the top of a remote end wall of the tank 54 for connection with an overflow discharge line 64.

Disposed within the container and rigid with the top wall 56 is a partition Wall 66 having a series of spaced apertures 68 adjacent the upper edge thereof with the lower edge of the partition wall 66 being detachably and slidably received between a pair of guide members 70 for dividing the container into two compartments with the inlet 52 being in one compartment and the outlet 62 being in the other compartment.

Mounted on the top 56 is an electric motor 72 having a vertically extending and elongated drive shaft 74 extending through the top wall 56 and into the first compartment with the shaft 74 terminating below the inlet opening 52 and having a mixing or churning blade 76 on the lower end thereof. The blade may be provided with inclined blades of a desired pitch for effectively grinding, churning, breaking up and mixing of the solid waste particles and paper with the liquid. The type of blade employed may be that type normally employed in devices for mixing or blending liquids or for use in chopping food particles. The motor 72 is supported from the top wall 56 wherein the agitator blade 76 will effectively disintegrate the solid Waste particles so that the chemical action may be effectively rendered in the second compartment. As shown clearly in Figure 1 an alternate inlet 61 and outlet 62 are provided on opposed corners of the tank 54 with one set of ports being closed by re movable caps 63. The top wall 56 may be reversed end for end which would enable either compartment to become the receiving compartment and the other compartment to become the discharging compartment. This construction will permit the boat owner to install the device in the most convenient manner and enable orientation of the inlet and outlet nearer the existing structure for easier attachment thereto.

In use of the device, after the toilet has been used, a small electric switch which may be conveniently located on the wall in front of the toilet and pressed and a delayed action switch will engage the electric motor for a predetermined length of time such as 35 to 45 seconds and completely blend the waste material with a liquid. This liquid will overflow from the first compartment into the second compartment where further chemical action takes place for additional cleaning of the Waste before it is emptied into the overboard discharge 64.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes Will readily. occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly,'all suitable modifications and equivalents may be resorted to, falling Within the scope of the invention as claimed.

What is claimed as new is as follows:

1. In combination with a marine toilet having a soil pump having a Water suction portion for supplying flushing water to said toilet, and a refuse portion for pumping waste material from said toilet, a chlorinating tank connected to said refuse portion and receiving said waste material therefrom, a container for a chlorinating liquid disposed alongside said toilet, and means for siphoning the liquid from said container into the Water suction portion of the soil pump in response to operation of said pump comprising a tubular siphoning line connecting the upper part of the container to said Water suction portion of said pump.

2. In combination with a marine toilet having a soil pump having a water suction portion for supplying flushing water to said toilet, and a refuse portion for pumping Waste material from said toilet, a container for a chlorinating liquid disposed alongside said toilet, and means for syphoning the liquid from said container into the 'water suction portion of the soil pump in response to operation of said pump comprising a tubular syphoning line connecting the upper part of the container to said water suction portion of said pump.
